[Twisted-Python] Debian unstable builder

[Tristan Seligmann]

Working on tickets such as #8180[1] and #8187[2] suggests that it would be
useful to have a builder running on Debian unstable (and/or other "bleeding
edge" distributions, most of them have something similar) in order to pick
up problematic changes like this sooner. #8180 is just a case of a newer
upstream release (OpenSSH 7.0 disables DSA key support by default), whereas
I think #8187 is a "distro policy" type thing (OpenSSL in Debian unstable
is compiled without SSLv3_METHOD support).

I don't think making such a builder be a supported platform would be
feasible (at least as things currently stand), but at least it would serve
as a canary for this sort of issue.

Thoughts?

I think the approved procedure for such a thing is just to write a PR for https://github.com/twisted-infra/braid. As you can see we do have some "canary" builders - particularly fedora 23 which just turned green quick make it supported before it breaks - on http://buildbot.twistedmatrix.com/boxes-unsupported?branch=trunk&num_builds=10 but we have purged a lot of the old, useless ones nobody was paying attention to.

So: yeah, go for it. If you'd like credentials so you can update the prod buildbot deployment, let me know ;)
